Of course, you can write large projects without const. Many other languages 
which are heavily used lack const. However, there is great benefit in having 
const, and you're most likely to derive that benefit from large projects where 
things are much more complex then you are with small projects where you can 
probably keep most of it in your head and/or you're the only one working on it. 
You can obviously do lots of quality programs without const, but having it is a 
big plus.
